Abstract
On March 10, 2016, the public comment draft Toxicological Review of Hexahydro-1,3,5-trinitro-1,3,5-triazine and the draft charge to external peer reviewers were released for public review and comment. The Toxicological Review and charge were reviewed internally by EPA and by other federal agencies and White House Offices before public release. Consistent with the May 2009 IRIS assessment development process, all written comments on IRIS assessments submitted by other federal agencies and White House Offices are made publicly available. Accordingly, interagency comments and the interagency science consultation materials provided to other agencies, including interagency review drafts of the IRIS Toxicological Review of Hexahydro-1,3,5-trinitro-1,3,5-triazine and the charge to external peer reviewers, are posted on this site.Hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX, or Royal Demolition eXplosive) is a military explosive with limited civilian uses. In the United States, RDX is produced at Army ammunition plants; it is not produced commercially.
An oral reference dose (RfD) and an oral cancer slope factor are currently available on IRIS. A reassessment of the human health effects of RDX, including both cancer effects and effects other than cancer, is being undertaken.
Impact/Purpose
EPA is undertaking an update of the Integrated Risk Information System (IRIS) health assessment for RDX. The outcome of this project is an updated Toxicological Review and IRIS Summary for RDX that will be entered into the IRIS database.Status
The hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) IRIS assessment was released for public comment in March 2016. Following the public comment period, the assessment will be revised taking into consideration public comments. The assessment will then be released for external peer review.Citation
